Lavxias-Suav Koom Tes Tshawb Fawb Chaw Rau Atmospheric Optics Ua Kev Txhim Kho Tshiab hauv Kev Ua Haujlwm Ntawm Hollow Cirrus hais

Tsis ntev los no, Sino-Russian Joint Research Center for Atmospheric Optics (JRCAO) tau ua tiav tshiab hauv kev sib koom tes tshawb fawb txog kev sim thiab theoretical kev tshawb fawb ntawm cirrus lidar detection. Cov txiaj ntsig tau luam tawm hauv Optics Express ntawm Optical Society of America (OSA) los ntawm pab pawg kws tshawb fawb Zhuzhu Wang los ntawm Lub Tsev Haujlwm Saib Xyuas Kev Kho Mob ntawm Hefei Institute of Physics, Suav Academy of Sciences, thiab pab pawg ntawm Prof. Alexander Konoshonkin los ntawm Lub koom haum ntawm Atmospheric Optics ntawm Lavxias teb sab Academy ntawm Sciences nyob rau hauv Zuyev, Russia.
Cirrus huab npog ntau dua 30% ntawm lub ntiaj teb airspace thiab yog ib qho ntawm cov tseem ceeb tshaj plaws cuam tshuam cov hluav taws xob sib npaug ntawm lub ntiaj teb-cua system. Yuav kom ua tau raws li qhov xav tau ntawm Lub Ntiaj Teb-Air System Model, qhov kev tshawb fawb tob ntawm cirrus microphysics yuav tsum tau ua. Cov kev sim kuaj pom yav dhau los feem ntau tsis quav ntsej txog cov dej khov nab kuab hauv cov huab cua cirrus, tsis tau ntau dua 50% ntawm cov hollow columnar ice crystals nyob rau hauv cov huab cua tiag tiag tau raug ntes los ntawm Huab Particle Imager (CPI). Txhawm rau kom paub meej qhov teeb meem no, pab pawg ua haujlwm tau tsim thawj Modal Hollow Ice Crystal (MHC) qauv rau nruab nrab latitudes kom haum rau cov lus piav qhia ntawm hollow ice crystals nyob rau hauv qhov xwm txheej, thiab pom tias thaum qhov sib xyaw ntawm cov khoom sib xyaw rau hollow particles ncav cuag. 50% thiab siab dua, nws muaj peev xwm sib txawv ntawm cov khoom sib txawv thiab cov khoom hollow raws li Lidar piv ntawm lub wavelength ntawm 1064 nm, xim piv ntawm 1064/532 nm, thiab de-polarized piv ntawm 532 nm, ntxiv kom tau qhov tseeb microparticles. kev sib xyaw ua ke kom tau txais qhov tseeb microphysical tsis zoo.
Txoj kev tshawb no tau txhawb nqa los ntawm National Natural Science Foundation ntawm Tuam Tshoj, Natural Science Foundation ntawm Anhui Xeev, thiab qhov program ntawm Suav Academy ntawm Sciences.
